This question is a nightmare. The right answer isn't really there. A short answer would be that New England didn't want a second war with Great Britain. There was a real gaffuffle about pressing American seaman into British Navy vessels that cause Jefferson to impose an embargo. All of this centered about the war of 1812.
The choice is between A and B. I would pick A, but I can't eliminate B.
C and D are not really amongst the reasons, particularly C.
The correct answer is Indus.
The Yellow River was an important part of Chinese civilization.

The Amazon River is located in South America, and was an important part of several different civilizations.
This shows that the only correct answer can be Indus River.
